Abstract

See full text

A fixing device having a cam and a contact member is configured to satisfy:

description='In-line Formulae' end='lead'D4>D2, anddescription='In-line Formulae' end='tail'

description='In-line Formulae' end='lead'D3−D4<D1−D2, description='In-line Formulae' end='tail'

where D1 and D2 are distances viewed along the rotation axis of the cam in a first state where a curved surface of the contact member engages with the first concave portion on of a cam, and D3 and D4 are distances viewed along the rotation axis in a second state where the curved surface engages with a second concave portion of the cam, D1 represents a distance from a most upstream contact point in the rotation direction to the rotation axis, D2 represents the shortest distance from the rotation axis to the curved surface, D3 represents a distance from a most upstream contact point in the rotation direction of the cam to the rotation axis, and D4 represents the shortest distance from the rotation axis to the curved surface.
